feat(pitch-deck): passwordless investor auth, audit logs, snapshots & PWA (#2)

Adds investor-facing access controls, persistence, and PWA support to the pitch deck:

- Passwordless magic-link auth (jose JWT + nodemailer SMTP)
- Per-investor audit logging (logins, slide views, assumption changes, chat)
- Financial model snapshot persistence (auto-save/restore per investor)
- PWA support (manifest, service worker, offline caching, branded icons)
- Safeguards: email watermark overlay, security headers, content protection,
  rate limiting, IP/new-IP detection, single active session per investor
- Admin API: invite, list investors, revoke, query audit logs
- pitch-deck service added to docker-compose.coolify.yml
